HP Quick Launch Buttons

The default windows which came with HP pavillion was XP. I uninstalled it and installed a copy of x64 vista ultimate and it comes with the eye-candy media center, so i planned on not installing the default HP Quickplay and DVD so the easy lauch button on the HP laptop are left alone...

I would like to reconfigure it to vista media center or anything else, i googled around to find the "HP Quick Lauch Buttons" Software can help me do it. Even after installing the vista compatble one from hp.com, the program wouldnt open. PLease help use the program or tell me some registry hack to reconfigure it, if its possible.. thnk you
